1-11 Model SGB Blender System Component Description

This section describes the various components of the blending system. The SGB

blending system is made up of the following components:

1-11-1 Material Supply Hoppers

1-11-2 Slide Gate Metering Assemblies

1-11-3 Weigh Hopper

1-11-4 Weigh Hopper Dump Valve

1-11-5 Mix Chamber

1-11-6 Operator Control Panel

SGB

Page 14 of 118 SGB Batch Blender with Mitsubishi Controller

1-11-1 Material Supply Hoppers

The material supply hoppers are located on top of the blender frame.

These hoppers store a supply of material for the individual metering

devices. They are sized based on the total throughput of the blender.

The SGB blending system does not include any level indication

devices on the unit. Optional low-level sensors are available. The

blender controller will alarm if it runs out of material while trying to

make a batch, but low-level sensors will alert floor personnel to the

problem sooner.

Each hopper is equipped with a sight glass and/or access door.

1-11-2 Slide Gate Metering Assemblies

Air operated slide gates are provided to meter the majority of pellet

ingredients on the SGB blender.

Important! The metering range assumes

1

/8” diameter free-flowing plastic

pellets weighing approximately 35 lbs./cu. ft. This is meant to be

an approximate sizing recommendation and can vary with

different bulk density resins, pellet configuration, etc.

A stroke limiter (included) can be installed on the metering gates to

limit their travel. This device decreases the stroke of the gate and

reduces the metering orifice of the valve. The unique diamond gate

provides a square opening at any stroke length, providing more

consistent flow from smaller valve openings than conventional slide

gates. This stroke limiter may be necessary to accurately meter low

percentage ingredients.

The air cylinders operating the slide gate are rugged, stainless steel

cylinders designed for industrial use.

DIAMOND GATE CLOSED

DIAMOND GATE 3/4 CLOSED

DIAMOND GATE 1/2 CLOSED

DIAMOND GATE OPEN

WARNING!

Slide gates create a pinch-point hazard.

Always disconnect and lockout all electrical power and

pneumatic (i.e. compressed air) sources prior to

servicing or cleaning any blender, including all SGB

Series models. Failure to do so may result in serious

injury.

The unique Sterling diamond gate provides a constant

aspect opening that remains square regardless of the

stroke length of the cylinder. This design provides a wider

cross sectional opening when approaching a closed

position, and provides better flow of plastic pellets out of

the opening.

Page 16 of 118 SGB Batch Blender with Mitsubishi Controller

Each of the diamond gate air cylinders is actuated by a solenoid valve,

which are controlled by the blender.

When the solenoid valve is energized, it opens the metering valve

cylinder. When the solenoid valve is de-energized, it closes the

metering valve cylinder.

If the power is interrupted to the blender, the metering valves will return

to the closed position, to prevent material from over-filling the weigh

hopper/mix chamber.

Important! If the blender is in metering mode with one of the slide gates open,

do not open the front door of the blender!

The safety switch shuts off the air supply to the blender. An open

feeder slide gate stays open, and an overflow of the weigh hopper

can occur!

SGB Batch Blender with Mitsubishi Controller Page 17 of 118

1-11-3 Weigh Hopper

The weigh hopper on the SGB blender is used to weigh each batch of

material, and includes an air-operated discharge valve. After the batch

is weighed and the level sensor in the lower mix section is uncovered,

the valve will open and discharge the batch into the mixer with the

existing blended material. The discharge valve is also provided with a

quick disconnect so the weigh hopper can be removed for cleaning.

On an SGB blender, the weigh hopper rests on each side on a

precision cantilever load cell. To remove the weigh hopper, lift the

hopper from the bottom, hold the discharge valve closed, and slide it

out once clear of the locating tab on the bracket above the load cell.

Once the hopper has been cleaned, reposition it onto the load cell

brackets, using care not to damage the load cells. Position the hopper

as close to the center position between the load cells as possible.

Important! Use care when replacing the weigh hopper, since the load cells are

delicate weighing instruments and can be easily damaged. Do not

use force to push in the weigh hopper. If it is positioned properly,

it will slide in very easily.

Load cells, if damaged, will have to be sent back to the

manufacturer for testing and evaluation.

Page 18 of 118 SGB Batch Blender with Mitsubishi Controller

1-11-4 Weigh Hopper Discharge Valve

The weigh hopper discharge valve holds the material until it is dumped

into the mixing section. The cylinder is actuated by a solenoid in the

valve stack on the rear of the blender.

In looking at the pneumatic circuit, you can see that the air regulator

controls the flow of air to the valve stack. When the weigh hopper

discharge cylinder solenoid valve is not electrically energized, it will

provide air pressure to the air cylinder and hold the shaft in an

extended position, holding the dump valve closed.

When the air cylinder is actuated, the air pressure to the dump valve

will be removed, causing it to open.

The air cylinder on the weigh hopper includes a spring return to allow

the cylinder to retract in the absence of air pressure on the cylinder.

This will cause the dump valve to open.

CAUTION! The pneumatic system used on the SGB, like all pneumatic

systems, is highly sensitive to oily, dirty, wet or contaminated air.

If oil, dirt, water, or any other air-borne contaminates enter the

system, the components could be damaged and injury to the

operator could result. A proper air supply must be supplied to the

blender.

When the safety circuit is disabled, the air pressure to the cylinder will

drop off by shutting off all the air supply to the valve stack with the pilot

operated master air valve. This will also cause the weigh hopper

discharge door to open.

SGB Batch Blender with Mitsubishi Controller Page 19 of 118

1-11-5 Mix Chamber

All of the Sterling batch blenders are equipped with an integral mix

chamber. The mix chamber holds multiple batches of material so any

variations in a batch are averaged over time.

1-11-5-1 Opti-Mixer™

The Opti-mixer™ is designed to provide bi-directional

mixing action and can be easily taken apart for cleaning.

This design is standard on all SGB blenders.

1-11-5-2 “HC” Mixer

The “HC” Mixer features an open wheel design and is best

used for multiple regrind materials and rigid pellets. It is

optional on all SGB models.

WARNING!

Never reach into the mix section of the blender without

disconnecting the power or air supply.

Serious injury can result from getting your hand caught in the

rotating mixer!

1-11-6 Operator Control Panel

The operator control panel includes a 8 foot (2.4 m) cable and can be

remote mounted (not recommended) adjacent to the blender. The

panel can be unplugged and removed if necessary.

The controller includes an embedded computer. This design provides

excellent blender performance along with an easily replaceable

control panel in the unlikely failure of any computer or electronic part.

The display menu format is very simple. After installation and setup,

simply enter in the recipe and start the blender.

If it is desired to have a local display and control of the blender closer

to a remote operator station, an optional RS422 remote control panel

(RCP) is available.
